Former National Security Adviser Susan Rice will no longer testify in front of the House Intelligence Committee on Tuesday over allegations that she was involved in “unmasking” President Trump associates, the Gateway Pundit reports.

This new development comes as the committee tries to get former United Nations Ambassador Samantha Power to testify as well.

Power has agreed to appear before the House panel before the August recess, according to CNN.

Lawmakers are expected to grill Rice about whether she requested to unmask the identities of Trump’s associates for political reasons.

The committee is leading one of many investigations into the Russian meddling in the 2016 presidential elections and claims that the Trump campaign colluded with the Russian government to defeat Hillary Clinton.

Among the names Rice reportedly unmasked was Trump’s former National Security Adviser Michael Flynn, who was fired after he misled Vice President Mike Pence about his conversations with Russia’s ambassador to the U.S. Sergey Kislyak.
